[WB24] [Answered] What is: Browser Synchronized Variable Attribute

The information message I am getting is

"The modifications of global 'gs_foo' will not be applied to the server. The <browser synchronized> variable attribute is used to apply the value to the server".

I can find no information in help about variable attributes or more specifically browser synchronized.

Hi,

If I remember correctly from reading the brochure, in older version you could use global server variables in browser code, but not modify them.
In v24 you can declare server variables as browser synchronized, then you can modify them in browser code.

Does anyone know what the syntax is for declaring a browser synchronized variable?

Answer: When declaring a global varilable such as "foo is string", type a comma at the end and you will get a list of variable attributes which include:

browser synchronized
business logic
controller
critical section
mapping
page name
report name
Serialize
server only
UI
unique key
useful
window name
xmlAttribute
xsdName
zombie

These are apparently called "Extension Attributes". If you search in the help index for "Extension Attribute" there is some documentation. However the "browser synchronized" attribute is not documented yet.

TO USE THIS ATTRIBUTE, go to Project, Description, Compilation Tab, and change "Browser WLanguage" to "Version 2".

Version 2 is defined in the help as follows:

WLanguage browser: Allows you to choose the browser framework used for the project. From version 22, WEBDEV proposes a new WLanguage framework for the browser code. This new version proposes a behavior close to server code and it completes the features of browser code. Important: to use the new WLanguage framework, the generation standard of pages must be defined in "HTML 5".
